Thanks for the advice. I bought my 05 gt used and it died on me 1 hour to driving it home. So I take it to a Subi dealer and they said the turbo just broke on the inside. (shouldn't they had diagnose lack oil in the first turbo, I feel like I'm being screwed or it could had been anything) I get a new oem one and it breaks 1 week into driving it, this time they said lack of oil was the caused and now they need to dismantle 90% of the engine ($1600 job) to see whats causing the lack of oil into the turbo. So, that made me think it could be the banjo bolt filter or something else?
I also ask them about the banjo bolt filter to see if I could take out the filter and they said not to touch it or my warranty will be voided.
I'm not sure if the previous owners did there OCI on time, should of done my research before I bought this car.
